Just bought the YP-U1Q 2GB. Great little player, but I have 2 questions now:

(1) I want to update the firmware so that the player supports SRS Wow. If I understood correctly, only the Korean firmware allows this.
Some time ago someone here posted a download link to Samsung Korea in this posthttp://www.anythingbutipod.com/forum...ead.php?t=9162
but that link appears to be dead.
Does anyone have the Korean firmware file (I guess that would be the Korean v1.50 or v1.25), or knows where to get them?

(2) I bought my YP-U1Q used and the battery is not exactly at full capacity anymore.
Now, I know it's a built-in Li-ion battery, but my question is: does anyone know whether it is at all possible to replace that battery? I'm fairly technically inclined, but before I open the player myself, I wonder if someone knows some stuff.
Like for example whether the battery is soldered or plugged in, and if a new battery (or one that fits & has the right specs) can be bought somewhere.
